HVAC Contractors in Ottawa

Ontario and federal rebate programs for heat pumps change frequently and can move the effective cost by thousands. Ask the contractor which programs they are currently registered to submit for - registration matters, because some rebates require the installer to be enrolled.

Planning estimates for Ontario, not quotes. Always get written quotes against the same written specification.

Questions to ask before you hire

Will you perform a heat loss and heat gain calculation, and can I see it?

Who on the crew holds the TSSA gas certificate, and at what level?

Is the equipment warranty conditional on registration or on installer certification?

What exactly is covered by your labour warranty, and for how long?

Does this quote include removal and disposal of the old equipment?

Which rebate programs are you registered to submit for, and do you handle the paperwork?

Warning signs

A replacement quote produced without anyone measuring anything or looking at your ductwork.

Sizing justified purely by matching the old unit.

Unsolicited door-to-door or phone offers for furnace or duct inspections. Ontario has a long history of aggressive HVAC door-to-door sales, and rules restricting it exist for good reason.
